The purpose of this study is to identify the types and sources of bibliographic enhancement data used by libraries, online booksellers, and social cataloging sites. Based on a content analysis of 210 bibliographic records collected from six bibliographic systems, this study identifies 21 types of bibliographic enhancement data and their sources. The typology can help libraries identify, select, use/reuse, and evaluate the bibliographic enhancement data that can be implemented in their catalogs. This study also found that libraries no longer count on catalogers to supply all the bibliographic data, but invite their staff and users to contribute data to their catalogs and incorporate data from external resources. Future research will interview users regarding their use of bibliographic enhancement data and their quality requirements for the data.
